Description

A kind of diesel engine particles cyclone filter

Technical field

The present invention relates to a kind of diesel engine particles cyclone filter, belong to diesel particulate filtration field.

Background technology

The total amount of pollutant for causing it to discharge that increases of motor vehicles is continuously increased, to atmosphere pollution important. Research shows that the noxious emission of vehicular engine is one of main source of atmosphere pollution:82%CO in U.S.'s air, 98% The waste gas that NOX and 58%HC discharges from automobile, even more serious, the 99%CO of Japan, 98%NOX and 36%HC come from car tail Gas.And in China, some metropolitan atmosphere pollution are gradually by coal smoke type car of turning direction tail gas pollution type, or as with two The contamination characteristics of person's synthesis.It is reported that compared with the past, vehicular emission is notable to the contribution rate of atmosphere pollution in recent years Increase.Motor vehicle is the pollution sources of a flowing, and the harmful substance that it is discharged mainly includes:It is carbon monoxide (CO), incomplete [2] such as hydrocarbon (HC), nitrogen oxides (NOX), soot (Soot) and the particulate matters (PM) of burning.Long Term Contact car tail Gas can directly stimulate human respiratory tract, make the immunity degradation of respiratory system, cause exposed population group's chronic bronchitis, breathing tired The incidence of disease rise of a series of symptoms such as hardly possible, decline in pulmonary function.More importantly the particulate matter in tail gas can cause to human body Chronic toxicity effect, the vehicle exhaust [3] especially using diesel oil as fuel.

Current global warming and problem of environmental pollution getting worse, atmosphere pollution have been to be concerned by more and more people.The world Various countries and area work up increasingly strict regulation one after another reduces emission limit, and higher requirement is proposed to engine technology. To meet 2008 Olympic Games, Beijing early excise the Europe IV standard and provided new fuel oil on January 1st, 2008.It is contemplated that more Add strict Abgasgesetz will Expedite the application in China

Diesel particle emissions are a complicated, dynamic compositions.It by soot, from unburned fuel and lubrication The compositions such as sulfate, the ash content in machine oil and the additive generated after the soluble organic fraction of oil, the combustion of sulfur in fuel. Each composition in the particle shared ratio regular meeting with the difference of the factors such as the operating mode feature of engine, technical merit and fuel qualities And change [5].It is uneven or incomplete that fuel combustion is primarily due to caused by diesel engine discharged particle, in height Aoxidized under warm anoxia condition, crack and formed [6].In engine operation process, outside air temperature, pressure, humidity, combustion Material, operating mode etc. can all influence to start the formation of organic pollutants.1.2 components and its endanger exhaust gas particulate (PM is i.e. Particulatematter) it is broadly divided into two kinds of components:A kind of its soluble organic fraction (SOF for being soluble in organic solution That is solubleorganicfraction), it is mainly derived from unburned fuel, lubricating oil and its intermediate product;Another kind is Dry basis insoluble in organic solution, mainly it is made up of the carbon and sulfate of free state.Because sulphates content is relatively fewer, one As be referred to as soot (DS is drysoot).It is extremely complex that harm of the particulate to environment and the mankind is mainly derived from chemical analysis Soluble composition, many of which polycyclic aromatic hydrocarbon has very strong " three cause " effect and bioconcentration, therefore receives significant attention. In 129 kinds " priority pollutants " that EPA in 1976 proposes, polycyclic arene compound has 16 kinds.Fine grained in air Thing (equivalent aerodynamic diameter<2.5 μm, represented with PM2.5) be to one of most toxic pollutant of health because It is enriched toxic heavy metal in air, acidic oxide, organic pollution, bacterium and virus, and major part can enter human body Lung alveolar deposit [7].Current many scholars are carried out to the source resolution of different diameter airborne particle, component in atmospheric environment Compare in-depth study [8], and investigate the important sources [9] for showing that automotive emission, automobile raising-dust are PM2.5, therefore The discharge of strict control diesel oil organic pollutants is into the task of top priority.

Diesel particulate filtration technology refers to that the particulate matter for reduction engine emission causes environmental pollution and it is entered The technology of row proper treatment, diesel particulate post-processing technology have been widely used as a kind of method of smoke filtration, its Principle is by settling, intercepting, the means such as filtering and remove particulate matter in diesel engine vent gas.Currently used diesel particulate mistake Device is filtered as stream wall type filtration, passes through the particulate matter in the micro porous filtration waste gas on inner structural wall face.The structure is although mistake Better performances are filtered, but manufacturing process is complicated, while flow wall-like structure and make it that the space availability ratio of the device is relatively low, it is equipped on bavin Larger resistance is produced in oil machine, it is larger to Diesel Engine Complete Machine performance impact.

For problem above, this paper presents a kind of reduction manufacturing process cost that disclosure satisfy that on the basis of strainability, Reduce pipe resistance and be capable of the diesel particulate filtration device of easy application.
